The release notes state that "Building GDB and GDBserver now requires a
C++17 compiler (for instance, GCC 9 or later)". Looks like we already
satisfy this requirement with GDB_DEP_NO_STD_FUTURE.
gdbserver now has a dependency on iconv.h, for uclibc configurations we
need to make sure this is satisfied.

Allows building the #mold linker, which can then be used in the
cross-toolchain by passing the -fuse-ld=mold to the gcc flags. It is
much faster than ld or gold.
This requires a C++20 compiler and cmake.
Initially implemented by Arnaud, and HC added configure check for cmake.
Outstanding task to validate compiler is C++20 compatible.

Both D and GNAT have their own runtimes (resp. libphotos and libada).
It is still possible to build the compiler proper without any runtime,
and have an external runtime installed later. This is most commonly
found in embedded systems.
An example for D is: https://github.com/KitsunebiGames/tinyd-rt
An example for Ada: https://github.com/Fabien-Chouteau/bare_runtime

Musl was marked experimental in commit 08d91d41 ("musl: config is broken
for !EXPERIMENTAL"). Most of the reasoning for that change no longer
applies and as it's been about 8 years it's time to let musl loose on
the world. Drop the `depends on EXPERIMENTAL` and update the sample
configs for aarch64 and x86_64.
For powerpc64 the ABI needs to be elfv2. Enforce this via the powerpc
config. Add a sample configuration for powerpc-unknown-linux-musl.

Linux kernel versions newer than 5.3 require rsync in order to export
the UAPI headers. Commit f441a6bf ("linux: Add dependency on rsync for
Linux >= 5.3") attempted to address this with a check that runs when
crosstool-ng is built. That had the downside that if crosstool-ng was
built and packaged on a machine that had rsync then run on a machine
that didn't then the build would fail due to the missing rsync.
Conversely if the first machine didn't have rsync installed when
crosstool-ng was built then we would not offer newer kernel versions.
We can address this by checking for rsync when the toolchain
configuration is updated using some functionality in the newer Kconfig
that we've updated to previously.

As of version 13.x GDB uses libtool for linking instead of g++ these
take different arguments for static linking. Commit 6146b5a6 ("use
-all-static when building a static gdb") attempted to deal with this but
had the effect of causing older GDB versions to fail to build
statically. Add a new internal flag GDB_CC_LD_LIBTOOL and use this to
decide whether to pass `-static` or `-all-static`.

Some m68k variants do have a MMU so the architecture can set
ARCH_USE_MMU. That means we can have a m68k-unknown-linux-gnu
configuration and that m68k-unknown-uclinux-uclibc needs to select
LIBC_UCLIBC_NG since it's no longer the default.

Versions of GNU make newer than 4.4 trigger a hang in versions of glibc
older than 2.31. As distros update to the newer GNU make version we'll
start seeing more and more reports of this hang. Fortunately we already
carry GNU make as a comp tool so all we need to do is select the right
version when needed.

This reverts commit 658f5e574f, which
was made without any justification, and prevents using crosstool-ng
even in decently recent distributions like Ubuntu 20.04 (which has
autoconf 2.69).
We have tested that ./bootstrap && ./configure --enable-local works
fine on Ubuntu 18.04, which uses autoconf 2.69 and automake 1.15, so
the existing requirements were enough.

This adds 3 new options to patch order:
* bundled + bundled_exp
* bundled + bundled_exp + local
* local + bundled + bundled_exp
The path for bundled experimental patches is: ${CT_LIB_DIR}/packages/${pkg_dir}/experimental
and patches that are still being reviewed, but not yet applied upstream
may be toggled with ENABLE_EXPERIMENTAL_BUNDLED_PATCHES.
Also fix modelines for editors on bootstrap and scripts/functions, and
fix mix whitespace in scripts/functions.

libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)

requirement (which appears to be the case on macOS).
